MiniMax released M3 today and the API is already live. Worth separating what comes from their own official model page versus what comes from the launch announcement, because some of the numbers are sourced differently. From the official model page: BrowseComp 83.5, ahead of Claude Opus 4.7 at 79.3. PostTrainBench 37.1, which ranks third behind Opus 4.7 at 42.4 and GPT-5.5 at 39.3. From the launch announcement: SWE-Bench Pro 59.0%, Terminal Bench 2.1 66.0%, MCP Atlas 74.2%. The headline "beats Opus" is BrowseComp-specific, not a general capability claim across all dimensions.
